I have no wired connection internet access on ubuntu 14.04 even though it is detected, my computer connected to the same router has.

what happens if you ping your router ping -c3 192.168.1.1? Or Google's DNS ping -c3 8.8.8.8? –  MariusMatutiae May 19 '14 at 16:21
    
3 packets sent, 3 received –  user324935 May 19 '14 at 16:32

Good. Then you do not have DNS nameservers. Add these two lines to /etc/resolv.conf:

  nameserver 8.8.8.8
  nameserver 8.8.4.4

and it should work.

That did work (it couldnt load videos on youtube) but after reboot is reset to: nameserver 8.8.8.8 nameserver 127.0.1.1 –  user324935 May 19 '14 at 16:55
    
@user324935 It should work then, doesn't it? –  MariusMatutiae May 19 '14 at 17:12
    
yes it is working properly now –  user324935 May 19 '14 at 17:37
